The value used in the large_futures example was not large enough to
trigger the lint given the default threshold.
The example also contained more code than necessary.
This PR changes the value size from 1kB to 16kB and reduces the example
in size.
adjust how closure/generator types are printed
I saw `&[closure@$DIR/issue-20862.rs:2:5]` and I thought it is a slice type, because that's usually what `&[_]` is... it took me a while to realize that this is just a confusing printer and actually there's no slice. Let's use something that cannot be mistaken for a regular type.

Allow `-Z treat-err-as-bug=0`
Makes `-Z treat-err-as-bug=0` behave as if the option wasn't present instead of asking the value to be ⩾ 1. This enables a quick on/off of the option, as you only need to change one character instead of removing the whole `-Z`.
Also update some text, e.g.
```bash
$ rustc -Z help | grep treat-err-as-bug
-Z treat-err-as-bug=val -- treat error number `val` that occurs as bug
```
where the value could be interpreted as an error code instead of an ordinal.

give FutureIncompatibilityReason variants more explicit names
Also make the `reason` field mandatory when declaring a lint, to make sure this is a deliberate decision.
tests/ui: Split large_moves.rs and move to lint/large_assignments
To make failing tests easier to debug with `--emit=mir`, etc.
Don't bother with `revisions: attribute option` for both tests though. Seems sufficient to just have that on one of the tests.
`git show -M --find-renames=40%` makes the diff easier to review. Or note that before this change we had one test with 4 errors, now we have 2 tests with 2 errors each.

Command: also print removed env vars
There is no real shell syntax for unsetting an env var so easily, so we have to make one up. But we already do that for showing the 'program' name so I hope that's okay here, too. No strong opinion on what that should look like, I went with `unset(VAR_NAME)` for now.
